A variable speed balance or teeter board including a platform, a fulcrum extending downwardly from the bottom of the platform into engagement with a supporting surface. The fulcrum comprising a variety of selectively used members of different shape and height for varying the angularity of the platform tilting action, and damping means comprising a plurality of members of different compressibility selectively or collectively interposed between the platform and the supporting surface for varying the speed of the tilting action of the platform upon application of unevenly distributed weight to the top of the platform, the particular damping member employed being dependent upon the ability of the individual using the balance board.

A balance board comprising: (a) a platform of rigid sheet material; (b) a fulcrum member secured to one face of said platform spaced a substantial distance from the periphery thereof and engaged with a supporting surface and adapted to permit parallel orientation of said platform with said supporting surface during use of the balance board, and, (c) damping means completely surrounding said fulcrum member disposed between said platform and the supporting surface, said damping means being in constant engagement with the supporting surface and substantially coextensive with said one face of the platform and extending substantially to the periphery thereof for controlling the speed of tilting of the platform when weight is unevenly distributed thereon.
